MALAQUIAS, MENSAGEIRO DA JUSTIÇA:UM ESTUDO A PARTIR DO QUARTO ORÁCULO (2,17-3,5)

O livro de Malaquias apresenta oráculos que conservam informações relevantes do período pós exílico sob o domínio da Pérsia e, especialmente, os problemas religiosos focalizando a displicência dos sacerdotes no cumprimento de suas funções e os problemas sociais apontando para um amplo movimento de opressão externa e interna. Esta pesquisa buscou verificar, no primeiro capítulo, como a mensagem de Malaquias através de sua forma e conteúdos visava aplacar as insatisfações internas dos grupos que habitavam o território de Judá. Neste capítulo, foram abordadas as discussões histórico-literárias sobre data, autoria, destinatários, forma do anúncio. Ainda procurou-se realizar levantamentos históricos verificando o sistema e as estruturas de opressão dos persas no território de Judá e também as faces da reorganização da sociedade de Judá. O segundo capítulo enfatizou, mais propriamente, o trabalho exegético no quarto oráculo (2,17-3,5). Neste pode-se verificar uma síntese dos temas centrais da mensagem de Malaquias: O juízo divino que viria pela negligência religiosa e que exigia compromissos com a justiça prática na vida do povo. A partir das discussões exegéticas buscou-se verificar como o profeta apresentou ao povo e aos sacerdotes quais seriam os agentes e as ações transformadoras que Javé promoveria para restaurar a justiça e o culto purificado. O terceiro capítulo apresenta um tema recorrente nos oráculos do livro de Malaquias: a justiça. Para isso, foram analisadas três perícopes que tratam o tema da justiça enfocadamente, as influências do sistema judicial persa na prática da justiça cotidiana em Judá e a realidade de opressão nos sistema de parentesco entre as famílias (clãs) que habitavam o território de Judá - (2,10-16; 2,17-3,5 e 3,13-21). A pesquisa de Malaquias aponta para um profeta engajado política e socialmente. O Mensageiro manteve os ideais proféticos e desejou reacender os valores da aliança entre o povo e fortalecer a confiança na ação de Javé que restauraria a justiça na prática cotidiana.(AU)

INTERVENÇÕES LÚDICO-MUSICAIS FRENTE AO ESTRESSE DE CRIANÇAS ACOLHIDAS VÍTIMAS DE VIOLÊNCIA DOMÉSTICA

Este estudo investiga o nível de estresse de crianças acolhidas vítimas de violência doméstica, antes e após intervenções lúdico-musicais em grupo, através de pesquisa exploratória descritiva de caráter quali-quantitativo. Caracteriza inicialmente a população da instituição, de 100 acolhidos, seu perfil sócio-demográfico, tipo de violência e motivo do acolhimento. Aplica a seguir, a Escala de Stress Infantil, ESI em 20 sujeitos, selecionados por conveniência. Realiza em seguida, intervenção com oito desses 20 participantes, também selecionados por conveniência, em oito sessões semanais, baseadas em técnicas de musicoterapia, que incluem relaxamento e atividades lúdicas, com abordagem winnicottiana. Ao final, realiza pós-teste da ESI nos 20 participantes. Os dados do perfil sócio-demográfico dos 100 acolhidos revelam 65% por cento do sexo feminino e 35% do masculino; faixa etária média de 6,66; violências sofridas por: negligência (52%); violência física (19%); dificuldade financeira (15%); abandono (12%); abuso sexual (2%). No pré-teste da ESI, foi constatado estresse em 80% dos casos, com predomínio nas meninas, sendo que o pós-teste não mostrou diferença significativa (p=0,944). A análise da intervenção mostrou-se positiva, revelando boa aceitação dos participantes, que expressaram seus sentimentos e emoções num setting acolhedor que promoveu a criatividade e a espontaneidade por meio de jogos sonoros, com abertura para novas experiências e socialização, caracterizando-se como medida de promoção da saúde da criança acolhida, com redução de seu estresse.

PERCEPÇÃO DE FAMÍLIA EM CRIANÇAS ABRIGADAS

A família é a base fundamental para o desenvolvimento saudável da personalidade. A vivência de afetos positivos permitirá à criança a capacidade de estabelecer novos vínculos, desenvolver auto-estima e confiança em si mesmo, tolerar frustrações e superar as angústias. Muitas crianças, no entanto, são privadas do convívio com seus familiares, por diversos motivos, como maus-tratos, abandono, negligência, abusos físico ou sexual, até a orfandade. Os abrigos existem para assegurar a estas crianças a garantia de seus direitos fundamentais até que retornem às suas famílias de origem ou até que sejam encaminhadas à adoção. O presente trabalho tem o objetivo de investigar a percepção de família das crianças abrigadas e ainda, identificar os principais conflitos e idealizações no que se refere à introjeção das figuras parentais. Trata-se de uma pesquisa qualitativa orientada pelo método clínico. Participaram deste estudo 04 crianças, com idade compreendida entre 08 e 10 anos, que viviam em uma casa-abrigo localizada na Zona Leste de São Paulo. Os procedimentos utilizados foram o Desenho da Família com Estória, além de observação, entrevistas abertas não-diretivas e dados fornecidos pela instituição. Os resultados encontrados indicam que, apesar de estarem separadas de suas famílias, estas crianças possuem internalizadas as figuras parentais e nutrem sentimentos ambivalentes em relação à identificação estabelecida com estes objetos. Entretanto, também foi identificada a presença de impulsos amorosos. Frente a isso, destaca-se o importante papel que as instituições ocupam na vida dessas crianças no sentido de poder oferecer às mesmas a oportunidade de sentirem-se amadas, acolhidas e cuidadas, desenvolvendo assim a capacidade de amar e estabelecer vínculos afetivos com outras pessoas. Os resultados apresentados limitam-se a essa amostra de quatro crianças, não tendo a pretensão de tecer generalizações acerca da percepção de família de todas as crianças abrigadas.

Technology valuation within the context of transfer collaborations with Chinese machine tool companies

The point of departure for this study was a recognition of the differences in suppliers' and acquirers' judgements of the value of technology when transferred between the two, and the significant impacts of technology valuation on the establishment of technology partnerships and effectiveness of technology collaborations. The perceptions, transfer strategies and objectives, perceived benefits and assessed technology contributions as well as associated costs and risks of both suppliers and acquirers were seen to be the core to these differences. This study hypothesised that the capability embodied in technology to yield future returns makes technology valuation distinct from the process of valuing manufacturing products. The study hence has gone beyond the dimensions of cost calculation and price determination that have been discussed in the existing literature, by taking a broader view of how to achieve and share future added value from transferred technology. The core of technology valuation was argued as the evaluation of the 'quality' of the capability (technology) in generating future value and the effectiveness of the transfer arrangement for best use of such a capability. A dynamic approach comprising future value generation and realisation within the context of specific forms of collaboration was therefore adopted. The research investigations focused on the UK and China machine tool industries, where there are many technology transfer activities and the value issue has already been recognised in practice. Data were gathered from three groups: machine tool manufacturing technology suppliers in the UK and acquirers in China, and machine tool users in China. Data collecting methods included questionnaire surveys and case studies within all the three groups. The study has focused on identifying and examining the major factors affecting value as well as their interactive effects on technology valuation from both the supplier's and acquirer's point of view. The survey results showed the perceptions and the assessments of the owner's value and transfer value from the supplier's and acquirer's point of view respectively. Benefits, costs and risks related to the technology transfer were the major factors affecting the value of technology. The impacts of transfer payment on the value of technology by the sharing of financial benefits, costs and risks between partners were assessed. The close relationship between technology valuation and transfer arrangements was established by which technical requirements and strategic implications were considered. The case studies reflected the research propositions and revealed that benefits, costs and risks in the financial, technical and strategic dimensions interacted in the process of technology valuation within the context of technology collaboration. Further to the assessment of factors affecting value, a technology valuation framework was developed which suggests that technology attributes for the enhancement of contributory factors and their contributions to the realisation of transfer objectives need to be measured and compared with the associated costs and risks. The study concluded that technology valuation is a dynamic process including the generation and sharing of future value and the interactions between financial, technical and strategic achievements.

Importance of tissue transglutaminase in repair of extracellular matrices and cell death of dermal fibroblasts after exposure to a solarium ultraviolet A source

Investigations were undertaken to study the role of the protein cross-linking enzyme tissue transglutaminase in changes associated with the extracellular matrix and in the cell death of human dermal fibroblasts following exposure to a solarium ultraviolet A source consisting of 98.8% ultraviolet A and 1.2% ultraviolet B. Exposure to nonlethal ultraviolet doses of 60 to 120 kJ per m2 resulted in increased tissue transglutaminase activity when measured either in cell homogenates, "in situ" by incorporation of fluorescein-cadaverine into the extracellular matrix or by changes in the epsilon(gamma-glutamyl) lysine cross-link. This increase in enzyme activity did not require de novo protein synthesis. Incorporation of fluorescein-cadaverine into matrix proteins was accompanied by the cross-linking of fibronectin and tissue transglutaminase into nonreducible high molecular weight polymers. Addition of exogenous tissue transglutaminase to cultured cells mimicking extensive cell leakage of the enzyme resulted in increased extracellular matrix deposition and a decreased rate of matrix turnover. Exposure of cells to 180 kJ per m2 resulted in 40% to 50% cell death with dying cells showing extensive tissue transglutaminase cross-linking of intracellular proteins and increased cross-linking of the surrounding extracellular matrix, the latter probably occurring as a result of cell leakage of tissue transglutaminase. These cells demonstrated negligible caspase activation and DNA fragmentation but maintained their cell morphology. In contrast, exposure of cells to 240 kJ per m2 resulted in increased cell death with caspase activation and some DNA fragmentation. These cells could be partially rescued from death by addition of caspase inhibitors. These data suggest that changes in cross-linking both in the intracellular and extracellular compartments elicited by tissue transglutaminase following exposure to ultraviolet provides a rapid tissue stabilization process following damage, but as such may be a contributory factor to the scarring process that results.

Maintenance strategies affecting equipment performance

Proper maintenance of plant items is crucial for the safe and profitable operation of process plants, The relevant maintenance policies fall into the following four categories: (i) preventivejopportunistic/breakdown replacement policies, (ii) inspection/inspection-repair-replacernent policies, (iii) restorative maintenance policies, and (iv) condition based maintenance policies, For correlating failure times of component equipnent and complete systems, the Weibull failure distribution has been used, A new powerful method, SEQLIM, has been proposed for the estimation of the Weibull parameters; particularly, when maintenance records contain very few failures and many successful operation times. When a system consists of a number of replaceable, ageing components, an opporturistic replacernent policy has been found to be cost-effective, A simple opportunistic rrodel has been developed. Inspection models with various objective functions have been investigated, It was found that, on the assumption of a negative exponential failure distribution, all models converge to the same optimal inspection interval; provided the safety components are very reliable and the demand rate is low, When deterioration becomes a contributory factor to same failures, periodic inspections, calculated from above models, are too frequent, A case of safety trip systems has been studied, A highly effective restorative maintenance policy can be developed if the performance of the equipment under this category can be related to some predictive modelling. A novel fouling model has been proposed to determine cleaning strategies of condensers, Condition-based maintenance policies have been investigated. A simple gauge has been designed for condition monitoring of relief valve springs. A typical case of an exothermic inert gas generation plant has been studied, to demonstrate how various policies can be applied to devise overall maintenance actions.

Managing the impact on biodiversity of supply chain companies

Industrial development has had a major role in creating the situation where bio-diverse materials and services essential for sustaining business are under threat. A key contributory factor to biodiversity decline comes from the cumulative impacts of extended supply chain business operations. In order to contribute to stopping this decline, the industrial world needs to form a better understanding of the way it utilizes the business and biodiversity agenda in its wider operations. This thesis investigates the perceptions and attitudes to biodiversity from government, society and a wide cross-section of industry. The research includes the extent of corporate attention to and use of environmental business tools and guidelines in reporting on biodiversity issues. A case study of three companies from different industrial sectors is undertaken to observe procurement and related environmental management of their supply chains. The use of accredited and non-accredited environmental management systems (EMS) are analysed as frameworks for introducing biodiversity aspects into supply chain management. The outcome is a methodology, which can be used either as a bespoke in-house biodiversity management system or within an accredited ISO 14001 EMS, for incorporating the assessment and management of the potential risks and opportunities involving environmental impacts on biodiversity of supply chain companies.

The effects of varying forms and degrees of government intervention upon the effective competitiveness of UK small businesses

This doctoral thesis responds to the need for greater understanding of small businesses and their inherent unique problem-types. Integral to the investigation is the theme that for governments to effectively influence small business, a sound understanding of the factors they are seeking to influence is essential. Moreover, the study, in its recognition of the many shortcomings in management research and, in particular that the research methods and approaches adopted often fail to give adequate understanding of issues under study, attempts to develop an innovative and creative research approach. The aim thus being to produce, not only advances in small business management knowledge from the standpoints of government policy makers and `lq recipient small business, but also insights into future potential research method for the continued development of that knowledge. The origins of the methodology lay in the non-acceptance of traditional philosophical positions in epistemology and ontology, with a philosophical standpoint of internal realism underpinning the research. Internal realism presents the basis for the potential co-existence of qualitative and quantitative research strategy and underlines the crucial contributory role of research method in provision of ultimate factual status of the assertions of research findings. The concept of epistemological bootstrapping is thus used to develop a `lq partial research framework to foothold case study research, thereby avoiding limitations of objectivism and brute inductivism. The major insights and issues highlighted by the `lq bootstrap, guide the researcher around the participant case studies. A novel attempt at contextualist (linked multi-level and processual) analysis was attempted in the major in-depth case study, with two further cases playing a support role and contributing to a balanced emphasis of empirical research within the context of time constraints inherent within part-time research.

Extended surface fluidized bed heat transfer

Experirnental data and theoretical calculation on the heat transfer performance of extended surface submerged: in shallow air fluidized beds ~ less than 150 mm, are presented. Energy t;ransferrence from the bed material was effected by water cooled tubes passing through the fins. The extended surface tested was either manufactured from square or radial copper fins silver soldered to a circular basic tube or commercially supplied, being of the crimped or extruded helical fin type. Performances are compared, for a wide range of geometric variables, bed configurations and fluidized materials, with plain and oval tubes operating under similar experimental conditions. A statistical analysis of all results, using a regression technique, has shown the relative importance of each significant variable. The bed to surface heat transfer coefficients are higher than those reported in earlier published work using finned tubes in much deeper beds and the heat transfer to the whole of the extended surface is at least as good as that previously reported for un-finned tubes. The improved performance is attributed partly to the absence of large bubbles in shallow beds and it is suggested that the improved circulation of the solids when constrained in the narrow passages between adjacent fins may be a contributory factor. Flow visualisation studies between a perspex extended surface and a fluidized bed using air at ambient temperatures, have demonstrated the effect of too small a fin spacing. Fin material and the bonding to the basic tube are more important in the optimisation of performance than in conventional convective applications because of the very much larger heat fluxes involved. A theoretical model of heat flow for a radial fin surface, provides data concerning the maximum heat transfer and minimum metal required to fulfil a given heat exchange duty. Results plotted in a series of charts aim at assisting the designer of shalJow fluidized beds.

Autonomic, biometric and oculomotor correlates of myopia in young adults

The principal work reported in this thesis is the examination of autonomic profile of ciliary muscle innervation as a risk factor in myopia development. Deficiency in sympathetic inhibitory control of accommodation has been proposed as a contributory factor in the development of late onset myopia (LOM). Complementary measurements of ocular biometry, oculomotor function and dynamic accommodation response were carried out on the same subject cohort, thus allowing cross-correlation of these factors with. autonomic profile. Subjects were undergraduate and postgraduate students of Aston University. A 2.5 year longitudinal study of refractive error progression in 40 subjects revealed the onset of LOM in 10, initially emmetropic, young adult subjects (age range 18-24 years) undertaking substantial amounts of near work. A controlled, double blind experimental protocol was conducted concurrently to measure post-task open-loop accommodative regression following distance (0 D) or near (3 D above baseline tonic accommodation) closed-loop tasks of short (10 second) or long (3 minute) duration. Closed-loop tasks consisted of observation of a high contrast Maltese cross target; open-loop conditions were imposed by observation of a 0.2 c/deg Difference of Gaussian target. Accommodation responses were recorded continuously at 42 Hz using a modified Shin-Nippon SRW-5000 open-view infra-red optometer. Blockade of the sympathetic branch of accommodative control was achieved by topical instillation of the non-selective b-adrenoceptor antagonist timolol maleate. Betaxolol hydrochloride (non-selective b1-adrenoceptor antagonist) and normal saline were employed as control agents. Retarded open-loop accommodative regression under b2 blockade following the 3 minute near task indicated the presence of sympathetic facility. Sympathetic inhibitory facility in accommodation control was found in similar proportions between LOM and stable emmetropic subjects. A cross-sectional study (N=60) of autonomic profile showed that sympathetic innervation of ciliary muscle is present in similar proportions between emmetropes, early-, and late-onset myopes. Sympathetic facility was identified in 27% of emmetropes, 21% of EOMs and 29% of LOMs.

Ophthalmic factors in dyslexia

Although the role of ophthalmic factors in dyslexia remains the subject of controversy, recent research has indicated that the correlates of dyslexia may include binocular dysfunction, unstable motor ocular dominance, a deficit of the transient visual subsystem, and an anomaly that can be treated with tinted lenses. These features, typically, have been studied in isolation and their inter-relationship has received little attention. The aim of the present research was to investigate ophthalmic factors in dyslexia, with a particular emphasis on the interaction between optometric variables. Further aims were to establish the most appropriate investigative techniques for optometric practice and to explore the relationship between optometric and psychometric variables. A pilot study was used to refine the experimental design for a subsequent detailed study of 39 children with a specific reading disability and 43 good readers, who were selected from 240 children. The groups were matched for age, sex, and performance IQ. The following factors emerged as correlates of dyslexia: slight impaired visual acuity; reduced vergence amplitudes; increased vergence instability; decreased accommodative amplitude; poor peformance at tests that were designed to assess the function of the transient visual system; and slightly slower performance at a non-verbal simulated reading visual search task. The `transient system deficit', as measured by reduced flicker sensitivity, was significantly associated with decreased accommodative and vergence amplitudes. This links the motor and sensory visual correlates of dyslexia. Although the binocular dysfunction was correlated with increased symptoms, the difference in the groups' simulated reading visual search task performance was largely attributable to psychometric variables. The results suggest tht optometric problems may be a contributory factor in dyslexia, but are unlikely to play a key causative role. Several optometric variables were confounded by psychometric parameters, and this interaction should be a priority for future investigation.
